PXI-8176RT - real time controller

[RPKumar]

I am planning to develop a pxi/scxi system in which i have to use data acquisition cards to acquire 4 channels at 6.5KS/s continuously and read 2000 samples from each channel,do some processing and display.Should I use the PXI 8176 Embedded controller (ordinary) or PXI 8176 RT embedded controller(real-time embedded) ?If I use the Real-time embedded controller is it required to use 7030/6040E for DAQ or only 6040E ?At present I am using the PCI 7030/6040E in a desktop PC to do the same.but I am not able to achieve the required rates of acquisiion when I do some processing and display.Only acquisition will work(without more processing).In this situation what is the ideal choice -to use ordinary embedded controller or real-time embedded con
troller?Also, I understand that the 7030 target will not run all functions like sound vis etc.does the embedded controller also has got this type of limitations?

Does your code require real-time *control* or *response*? It is possible to acquire data reliably at the rates you specify under Windows with a regular DAQ board if acquisition and display of data is the only concern. LabVIEW Real-Time is generally used more for when deterministic code response time is necessary.

To simply acquire, process and display data, I would recommend the PXI-8176 with Windows, and a regular PXI-6040E device. On the plus side, since you would be running your code under Windows, you would have access to all of the LabVIEW for Windows functionality, but since you mention the Sound VIs, keep in mind that our PXI controllers do not have sound cards on them, so you'd basically be talking about a PC speaker beep at most.

If you do require the
deterministic code response that you currently have with your 7030, just running more quickly, the PXI-8176 RT would do the job. You would still need just a PXI-6040E, and you would not be able to use a PXI-7030/6040E in this situation. Here you are running your code on the RT OS, so the sound VIs would not work. However, file I/O, something that your 7030 board will not support, would work on the PXI-8176 even in RT mode.

Hope this helps.
